Korean Anxiety Sensitivity Index-Revised: its factor structure, reliability, and validity in clinical and nonclinical samples.

The factor structure and convergent and discriminant validity of the Anxiety Sensitivity Index-Revised (ASI-R) were examined in a community sample, a student sample, and patients with panic disorder in Korea. Results from a confirmatory factor analysis (CFA) comparing our data to factor solutions commonly reported as representative of European American populations indicated a poor fit. A subsequent exploratory factor analysis (EFA) indicated that a four-factor solution provided the best fit. Correlations between the ASI-R and anxiety measures were moderately high, providing evidence of convergent validity. Implications for assessment with Koreans are discussed.
